1881 D&RG Whistle Signal

The first train whistles for Chama.
We will never hear these signals on a recording but some of the Model Railroader who do the early years might wish to use them. "Railroad Gazete" in 1881 made a giant page layout to compare the entire country and numbered various reasons. The D&RG was as follows;
#1 Apply Brakes Stop 0
#2 Release Brakes Start 00
#3 Back 000
#4 Approach Highway Xing not in rules on D&RG
#6 To recall Flagman 0000
#7 Approaching station ____
#9 Note flag on engine 00000
#10 Answer to #9 00
#11 Cattle on track --------- repete
#13 Train has parted (___0)+(___0) repete
And that was it! Later years can be found in the Rule books but they are hard to come by.
